【摘要】：以高純環(huán)烷酸為原料合成了系列酰胺咪唑啉季銨鹽水溶性緩蝕劑,探討了其咪唑啉環(huán)N(1)原子上取代基與緩蝕性能之間的關(guān)系。采用取代基電子效應(yīng)法和碳鋼掛片失重法,從理論與實(shí)驗(yàn)兩方面探討了酰胺咪唑啉季銨鹽對碳鋼的緩蝕性能。利用數(shù)理統(tǒng)計(jì)方法得出,其緩蝕效率(η)與基團(tuán)極化效應(yīng)參數(shù)(PEIx)和—C=C—鍵效應(yīng)指示變量D之間符合定量線性關(guān)系η=a+b PEIx+c D(a,b,c為常數(shù)),相關(guān)系數(shù)R≥0.996。該研究成果,能為離子型緩蝕劑分子設(shè)計(jì)提供一種簡便易行的新方法,為找到具有更佳緩蝕性能的新型咪唑啉緩蝕劑提供參考。
[Abstract]:A series of water soluble corrosion inhibitors of imidazoline quaternary ammonium salt were synthesized from high purity naphthenic acid. The relationship between the suppressive group of N (1) atom and the corrosion inhibition property of imidazoline ring N (1) was discussed. The corrosion inhibition properties of aminoimidazoline quaternary ammonium salt on carbon steel were studied theoretically and experimentally by means of substitution electron effect method and hanging plate weight loss method. By means of mathematical statistics, it is found that the inhibition efficiency (畏) is in accordance with the quantitative linear relation 畏 = a b PEIx c D (a BJ c between the parameters of group polarization effect (PEIx) and C-C bond effect indicator variable D, and the correlation coefficient R 鈮，
